Hide Names from Students

A peer graded assignment can be graded anonymously. In this
case the names (and any photos) of the students doing the grading
are not shown. Only the (file) names of the submissions are used to identify
the pieces of work being graded.

When the peer graded assignment is not graded anonymously, the
pieces of work are shown with the names (and any photos) of the
students who submitted the work. This may lead to bias in the gradings.

Note that if the teacher's grades are shown to the students these are
never shown anonymously.
